Programming Assistance

elvis’s programming assistance capabilities are described in this section.

Edit-Compile Speedup

elvis provides commands that make it easier to stay within the editor while working on a program. You can recompile a single file, rebuild your entire program, and work through compiler errors one at a time. The elvis commands are summarized in Table 17-10.

CommandOptionFunction
cc[!] [args]ccprg

Run the C compiler. Useful for recompiling an individual file.

mak[e][!] [args]makeprg

Recompile everything that needs recompiling (usually via make).

er[rlist][!] [file]

The cc command recompiles an individual source file. You run it from the colon command line. For example, if you are editing the file hello.c and you type :cc, elvis will compile hello.c for you.

If you supply additional arguments to the :cc command, those arguments will be passed on to the C compiler. In this case, you need to supply all the arguments, including the filename.

The :cc command works by executing the text of the ccprg option. The default value is "cc ($1?$1:$2)". elvis sets $2 to the name of the current source file, and $1 to the arguments you give to the :cc command. The value of ccprg thus uses your arguments if they are present; otherwise, it just passes the current file’s name to the system cc command. (You can, of course, change ccprg to suit your taste.)

Similarly, the :make command is intended to recompile everything ...
